Specification of Letters Patent.

Patented Feb. 8, 1916.

Application filed October 29, 1914. Serial No. 869,341. I

To all whom it may concern:

Be it known that I, MAXIMILIAN J. FUCHS, citizenof the United States, residing at Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Metal-Reducing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a preliminary metal reducing machine adapted for use in the manufacture of bronze owder.

The object of my invention is to provide a beating machine that will first reduce the coarse metal into thin flakes or other like proper condition for the final boaters that reduce the metal into proper commercial bronze powder.

Referring to the. drawings: Figure 1 represents a side elevation of the machine; Fig. 2 is a broken central sectional View of the base and broken view of the boaters; Fig. 3 is an enlarged detail plan of three of the anvils; Fig. 4 isan enlarged broken cross sectional view of the base on line 44 of Fig. 2, broken view of two of the boaters connected with the metal agitators adapted to push the coarse metal under the initial boaters of the series of boaters; and Fig. 5 is an enlarged detail view of one of the agitators and broken sectional "iow of the base.

The machine is divided into the two compartments 12, and each is equipped with boaters 34 arranged in pairs as shown in Fig. 4, the front view of boaters only being shown in Figs. 1 and 2. Parallel shafts (one) 5 is shown in Fi 1 carrying a series of cam lifters 6 contacting with the collars 7 carried by the beatersl This being a common construction of beating machines forms no part of my invention. On the ends of shaft 5 are the gears 8-9 adapted to mesh with similar--gears (not shown) on the shaft (not shown) parallel to shaft 5 and equipped with cam lifters for the rear row of boaters. The shaft 5 is driven from a source of power (not shown) through the medium of pulley 10. I

The metal base 11 carries the series of pairs of'anvils'12 in the compartment 1 set in circular pockets or recesses 13 in the floor 14 of the inclined run-way 15. In the second compartment are located, in similar pockets 16 in the floor 17 of the inclined run-way 18, the pairs of anvils 19. In the first compartment and on each side of the inclined run-way Figs. 4 and 5 are located the aggtator bars 20 operatively connected to a pair f the boaters by the levers 21. These bars carry the points 22 adapted to be located in.the spaces a, Fig. 3 of the floor of the run-way, and as the bars 20 are reciprocated by the vertical movement of the boaters, these points will prevent lodgment of the coarse metal in the aforesaid spaces.

The coarse metal is first placed in the hopper 23 in which is located the endless conveyor 24 mounted on the sprockets 25 rotated through the medium of the sprocket chain 26, which chain connects with the small sprocket wheel 27 on the shaft 5 with the large sprocket wheel 28 on shaft 29 carrying the worm 30 and from thence through the tightening Worm gear 31 belt 32 to the pulley 33. The forward end of the conveyor is adapted to be lifted by the cord 24 for the insertion of large pieces of metal.

The coarse metal is discharged by the conveyor into the chute 34 Fig. 1 which conmeets with the inclined passage'35 Fig. 2

to the first set of boaters where the heaviest stamping is done. It will be noted that the anvils 12 are arranged in steps, each 'pair of anvils successively occupying a lower plane than the preceding pair. The initial boaters in the series of heaters in this first compartment will crush or break up the the flakes have passed the agitator, they will "have become so reduced in size and light that the jar of the boaters on the anvils will be suflicient to cause the fine par ticles to freely circulate over the anvils.

After passing through the first series of heaters in chamber 1, the reduced metal is gradually crowded over into the passage 36 and into the next compartment 2 to be still further reduced by the series of boaters and anvils located therein. Those anvils,

like those of the first compartment are stepped off and the metal is gradually carried down the inclined run-way and through the passage way 37 into a rotating sifter (not shown) and the fine metal passed through the sifter is ready for the heaters that are to reduce it to commercial bronze powder.

The heaters above described are intended to do the preliminary work for the heatersthat produce the commercial bronze powder which latter heaters may be located away from the preliminary heaters or they may be situated at the end of the preliminary heaters to automatically receive the fine metal from the sifter, and means, common to machines of this character, could be employed to convey the coarse metal remaining in the sifter back to the hopper 23.

The principal feature of the invention resides in the stepped arrangement of the anvils located in an inclined run-way, an arrangement best adapted to give the same result in a single machine that would otherwise require as many different machines as there are individual heaters in the combined machine shown. The stepped arrangement of the anvils in the inclined run-way allows the metal to flow gradually by gravity from one set of anvils to another set, reducing the metal by degrees in its passage down the incline .run-way.

W'hile I show the machine divided into two compartments, it will be understood that the number of compartments could be increased if desired.

It is not necessary that the agitator bars be actuated from the heaters as shown, as they can be operated from any other desirable source.

It will be seen from the drawings that the anvils in each compartment are set'so close together that lodgment of material between them is impossible, and the arrangement is such that in each compartment, practically, a continuous inclined anvil is formed. And the passagewavs connecting the compartments, are so inclined and disposed that they lead directly from the surface of the last anvil in the preceding compartment, to the surface of the first anvil in the next compartment, and the angle of inclination is such as to deliver the entire contents of a compartment by gravity.

As aforesaid, this invention is primarily intended for the production of commercial bronze powder, and the invention provides a machine in which the entire operation is progressive, and requires no manual handling, or transferring to other machines to complete the reduction of the material. In the drawings, but two beating compartments are shown, but as stated in the foregoing, more beating compartments may be, and frequently are, used, each compartment,

of course, being connected by an inclined passage-way of the type described. r

The type of heaters employed is conventionally shown in the drawings, but the crushing effects of the same are graduated in the different compartments. For exam ple, in the first compartment, the material is received in a coarse condition, and in this compartment comparatively heavy beaters are employed to effect the initial reduction; from the first compartment, the material gravitates through the connecting passage-way to the next compartment and therein lighter heaters are employed to effeet a further reduction of the material, and in the event of further compartments being utilized, still lighter heaters are used, and so on throughout all the compartments. The reason for the variations in the force of the heaters in the several compartments is that the material delivered to the first compartment is quite coarse, and the beaters are necessarily heavy in order to effect the proper reduction of the material for the next set of heaters. The material being partially reduced in the first compartment, obviously the next treatment need not be as forcible as the initial treatment.

viously the action of the heavy heaters in the first compartment has a tendency to throw the metal to one side, and to prevent the metal thrown aside gravitating through the compartment and into the next compartment, the agitators 20 are employed to keep the metal under the heaters.

In the other 1 compartments, agitators are not required, as the heaters do not act on the material 5 wlth sufficient force to jar the material from I the anvils.

The object of using the heaters in sets of j twos or pairs is that the machine is correspondingly shortened thereby.

charge from the machine. A machine forthis purpose must of necessity require a very 1 heavy cast iron base to support the blow of;

the heaters, so that a machine thus extendedf for a single line of heaters and the extra floor space required would add greatly to; the cost of production, especially where a; large number of machines must be employedg in order to carry on a successful business. f

While only two compartments are shown simply to illustrate the operation of the ma-; chine, it is obvious that a sufii'cient number ofi compartments, as before mentioned, can be employed to give the desired result. practice it is found that four compartments; with heaters in each compartment, will deliver commercial bronze powder at the last compartment from the coarse material fed,

into the first compartment. It is advisable to separate the machine into these several compartments to prevent the material from one compartment passing into the next compartment before it has been properly reduced for itsreception thereto. The heavy jar of the heaters on their anvils will necessarily' cause some of the fine material to float above the anvils and prematurely workdown to the next set of heaters were it not for the separating partitions whose restricted openings will suffice to deliver the finished product of any of the compartments from which the material is being delivered and when it is prepared for delivery, a result not otherwise obtainable were the several series of heaters located in one long compartment.

Having thus described my invention what I claim is 1. A device of the character described having an inclined runway with anvils, heaters for said anvils, and movable means located adjacent and within the side walls of said runway for confining the material treated to the anvils.

2. A machine of the character described comprising a base provided with a plurality of compartments, the compartments being disposed indifferent horizontal planes and equipped with heaters, means for operating the heaters, an inclined runway forming the floor of each compartment, a series of stepped-off anvils in each compartment, an

inclined passage connecting the compartments, a delivery passage in the last compartment, and means for feeding material to the first compartment.

3. A metal reducing machine comprising a plurality of longitudinally alined separate compartments, the compartments having inof the last anvils in the preceding compart ment to the top surfaces of the first anvils in the next compartment, heaters cooperating with the anvils of each compartment, and means adjacent the side walls of the first compartment for confining the material being treated to the anvils.

In testimony whereof I afiix my signature in presence of two witnesses.
